9902.09.08 - Alkyl (C16-C18)polyethyleneglycol tetra decylene glycol ether (CAS No. 96081-39-9) (provided for in subheading 3402.13.10)

This HTS category, 9902.09.08, specifically covers Alkyl (C16-C18)polyethyleneglycol tetradecylene glycol ether, identified by CAS Number 96081-39-9. This compound is a type of non-ionic surfactant with a specific chemical structure, where an alkyl chain of 16 to 18 carbon atoms is ethoxylated and further reacted with tetradecylene glycol. Its inclusion within Chapter 99 signifies that it is subject to temporary legislation, temporary modifications proclaimed pursuant to trade agreements legislation, or additional import restrictions.

As this is a leaf node within the HTS, there are no further subdivisions directly under this code. Its classification is distinct from other temporary provisions found in Chapter 99, which may cover different goods or apply different types of trade restrictions. Furthermore, the parent context indicates that while this specific provision is temporary, the underlying good (Alkyl (C16-C18)polyethyleneglycol tetradecylene glycol ether) is generally provided for in subheading 3402.13.10, which classifies non-ionic surfactants. Therefore, this 9902 code serves to modify the standard treatment of that surfactant under specific, temporary circumstances.
